right wing keeps dipping down

[Megatherion]

I am having the same problem, even with all realism settings turned off. All speeds and altitudes and trim settings, the plane constantly banks right. I noticed that in the no cockpit view(ctrl F1), the very bottom left HUD "ball" that show the stick position shows the ball a tiny bit to the right of center, thus the right banking. Another thing I found is that when I hold the joystick a tiny bit left and get the ball centered and the plane flying level, then pause, then let go of the stick, then unpause, the plane flies level until any stick input is given, then it's back to banking right again. I tried 2 joysticks, Saitek X65F ($400) and Logitech Extreme 3D Pro ($10) and the same thing on both sticks.Trim has absolutely no effect on this banking. Sure hope this gets fixed.
